我省自然条件比较适宜的培菌时间为7～10月,在10月以后接的栽培种,由于温度低,一般11～1月气温在10～-10℃,菌丝生长缓慢,很难管理好,常常需要3～4个月的时间才能长到瓶底,或是压块后迟迟不出菇。 1981年,我区城关公社东石大队香菇厂,在11月接上了1万瓶“7402”香菇栽培种。为了在气温低的情况下,保证菌丝正常生长,我们将这批栽培种 Natural conditions in our province more suitable bacteria culture time is from July to October, in October after planting, due to low temperature, the general 11 to January temperature of 10 ~ -10 ℃, mycelial growth slow, it is difficult to manage Good, often takes 3 to 4 months to grow to the bottom of the bottle, or after the block does not delay fruiting. In 1981, our district Chengguan commune East Stone Brigade mushroom factory, in November received 10,000 bottles of “7402” mushroom cultivation. In order to ensure the normal growth of mycelium in the case of low temperatures, we will these cultivars
